It seems Microsoft has made the biggest blunder of E3 this year, accidentally posting the reveal for Halo 4 on their website, Xbox.com. Don’t expect it to stay there for long.

“The news millions of Halo fans have waited for: Halo 4 is on the way. But that’s not all…” read the Xbox.com E3 page. Along with the accidental Halo 4 slip, they also revealed these titles will be at their conference:

Kinect Star Wars
“”Feel the Force like never before as Kinect brings you into the Star Wars universe”

Dance Central 2
“New songs and new moves in the sequel to the best-selling Kinect dance game”

Halo: Combat Evolved Anniversary
“The epic game that launched a universe, remastered for a new generation”

Kinect Sports Season 2
“Kinect puts you in the game for baseball, golf, skiing, tennis, and more”
